Today’s world’s societies are becoming more and more dependent on open networks such as the Internet, where commercial activities, business transactions and government services are realized. This has led to the fast development of new cyber threats and numerous information security issues, which are exploited by cyber criminals. The inability to provide trusted secure services in contemporary computer network technologies has a tremendous socio-economic impact on global enterprises as well as individuals.

Moreover, frequently occurring international frauds make it necessary to conduct investigations of facts across international borders. Such examinations are often subject to different jurisdictions and legal systems. The Internet has acted as an alternate avenue for the criminals to conduct their activities and launch attacks with relative anonymity.

This poses new challenges for law enforcement policies and requires the services of digital forensics to combat the increasing number of cybercrimes. Digital forensics is a recently emerged research area and has attracted the attention of computer professionals, law enforcement experts and practitioners. It is a multidisciplinary area that includes, for example, law, computer science, finance, networking, data mining and criminal justice. However, despite increased interest, the field still faces diverse challenges, most commonly related to the efficiency of the digital evidence processing and the resulting forensic procedures.
